SPECEFIGATION forming part of Letters Patent No. 355,001, dated December28, 1886.

Application filedd'une 14, 1886. Serial No. 205.l07. (No model.)

To aZZ whom it may concern.-

Be it known that I, JOHN CASEY, of Boston, in the county of Suffolk, ofthe Commonwealth of Massachusetts, have invented a new and usefulImprovement in Upright Piano-Fortes; and I do hereby declare the same tobe described in the following specification, and represented in theaccompanying drawings, of which- Figure 1 is a vertical section of partof a piano-front with its music-rest and its operative mechanism inaccordance with my invention, the nature of which is defined in theclaim hereinafter presented. In this figure the said music-rest is shownas out, or in a po sition for use; but in Fig. 2, which is a similarsection, the said rest is shown as closed. Fig. 3 is a transversesection of the music-rest and its supporting spring-catch.

The said 1nusic-rest is shown at A as provided at its lower edge with amovable shelf, B, hinged to the said rest, which at top is hinged to thepianofront piece 0.

At the back of the rest, and in a groove, (1, formed lengthwise therein,is a metallic rod, D, which, near its upper end, extends loosely througha tubular guide, b, fastened to the rest. At its lower end the said rodis hinged to an arm or projection, 0, extending from the back side andedge of the shelf. A red or strut, E, hinged at its lower end to thefrontpiece 0, in rear of the music-rest, extends upward, and, at itsupper end, is pivoted to the rod D. In rear of the said rod E, andfastened to the front-piece O, is a spring, F, that at its free endbears against the strut E.

To the back of the music-rest, at its lower part, there is fixed aspringl'a-tch, G, which extends across the rod D, and is provided with astud, e, to, enter either of two holes, f and 9, made in said rod. shankgoing through the music-rest and bear- A push-button, H, has its ingagainst the spring-catch. On pressing in the said push-button thespringcatch may be forced out of engagement with the rod. Bya personapplying the thumb or forefinger of his hand against the head of thepuslrbutton and pressing it inwardly, when the music-rest isoutorin theinclined position shown in Fig. 1, the said catch may not only be forcedout of engagement with the rod D, but the music-rest, as well as itsshelf, may be forced backward into a vertical position'against thefront-piece, the shelf while moving backward being caused to turndownward from a position at a right angle to the rack into one in thesame plane with it. Both the restand shelf, when baclmvill be held intheir positions by the spring-catch engaging with the rod D. If when therest is back the push-button be pressed inward, so as to force thespring-catch out of engagement with the rod D, the spring will at oncebe free to act, and by its pressure on the strut will force itoutward,and thereby cause the musicrest to move forward and the rod D atthe same time to descend and cause the shelf to turn into a position ata right angle to the music'rest.

I clairn-- In combination with the upright-piano-front piece, themusierest hinged thereto and the shelf hinged to the musicrest, the armprojectiug from such shelf, the slide-rod hinged to such arm andadapted, as described, to the music-rest, the strut or rod hinged to thesliderod and to the front-piece, the spring secured to such front-pieceand bearing against the strut, and the spring-catch and its operatingpush-button applied to the musierest, all being substantially as setforth.
